I don't even think that's particularly controversial. The concentration of tech startups in SF has been devastating for the city, and has distorted every aspect of early-stage tech startups for years. And frankly, YC bears a rather large proportion of the blame for this.

San Francisco was like this before the current tech boom, too- http://www.salon.com/1999/11/03/sf/ it dates back to the 1980s- http://projects.sfchronicle.com/sf-homeless/overview/

Really nothing to do with YC.

I wouldn't be so quick to blame YC. YC actually encourages founders to be smart about their funding money and not spend a premium just to HQ in SF if at all possible. Problem is a lot of founders just feel so inclined to work in SF.
